Some Bash tips (command line)
Use brackets
-
Brackets allow to repeat a text.
For example:
echo {voit,piq,ray}urewill write voiture piqure rayure. This can be very handy for the command line
cp httpd.conf{,.bak}will dopy the httpd.conf file in httpd.conf.bak or
diff /etc/httpd/conf/httpd.conf{.bak,}will do a "diff" command between httpd.conf.bak and httpd.conf files.
Date and Time in a variable
-
To put it in a variable date, and time is simple:
TheDate=`date +"%Y/%m/%d %H:%M:%S"`Variable $TheDate will contains date and time.
